I dont think theres anything in the song that hints at anyone being mad at anyone. I think its more mature than this.

Firstly she says "I know what I know" meaning that she basically has such a deep and intelligent understanding of relationships (more than likely through experience). And what she knows is that he is indeed seeing someone else. Not just screwing around, but he is actually developing some deep feelings for the other "one". The other chick more than likely knows about Karen as well, but probably lingers in the back until the final outcome.

To sum it all up Karen knows that the guy loves her from the 'weve been together all these years' aspect but the flame ran out whether it be from arguments or whatever. Karen also knows that the other girl will turn into the only thing he ever knew, as to say that in time he wont have to feel bad about leaving Karen as much, just as time heals all other wounds to.

Shes not trying to convince the guy to stay with her because she knows that she messed up with him in the past with maybe lack of attention, or arguing, or nagging, and kind of pushed him away. As well, he probably did his share to. This may be far fetched for some, but how would you explain not being made that your significant other fell for someone else?

Anyway, Karen can tell the guy is really confused. Should he stay in this same old worn out relationship acting happy and guessing what could have happened with the 'other girl', or should he go ahead and face the pain of loosing his long time companion, Karen, and will the other girl screw him. Karen is hurt as well, but she is really making it a little easier for both of them by just setting him free because the fact that she allready knows, and the fact that he caint tell her is eating them both inside.

Before she probably kept this from him and hoped that it would maybe just go away or whatever, but know the same look he had in his eyes when he and Karen were fresh is the same look he has now.........."caint say why I kept this from ya, my those quiet eyes become ya". She probably caught him daydreaming a couple of times or something. Or maybe she can see in his eyes that his internal confusion and turmoil is slowly deteriorating him because he truly loves Karen, but caint help the way he feels about the 'other girl'.

Try listening to it after reading this and see if it makes sense.

Its basically a mature and understanding break up song. So the moral is.... well it could go south really quick so do what you can while you still have his, or her attention.
